"The driver wasn't familiar with the shard" bloody hell, you can see it from most of London (in fact, it is the tallest building in Europe).

If I wanted to do that journey in a hurry, that is a terrible route, you could probably cycle the route the other taxi's took more quickly.

Disclaimer: I walk the same journey mentioned every day, working on off fleet street and living in Bermondsey.

I don't often use taxis and I've never used Uber so I'm not specifically cheering for one side or the other. I know this isn't presented as an exhaustive study but basing the "results" on a single trip by each service doesn't prove much.

Another instance of "anecdata."
